Have I made a serous mistake about the Jehovah's Witness disfellowship doctrine?

Not sure why no JW's answered but I will try. I don't see any serious errors. If you violate the doctrines you get kicked out. That's right. If you die an apostate you don't make it into paradise. That's right. If you question the servant sounds like pretty much the apostate thing again. As far as I can tell you got it right. Of course you made it sound like it was easy. They don't kick you out at the drop of a hat. They talk to you, counsel you, see if you are repentant or not, it's a process, not just a judgment. But you've got the basics. I do want to clarify that not ALL JW's are bad people and not all congregations are corrupt. That's like saying ALL police are corrupt or ALL priests molest kids. Some of them do but the majority don't. I was raised a JW and I never saw corruption or abuse of power or anything like that. I'm not saying it doesn't happen but one person's experience is not indicative of the whole religion. It's not a cult and it's not scary. It's just a bit controlling and weird to most people.
